João Pedro Battistella Nadas 9564900909 feat: editor font-size match, hot model default, Shift-H/L nav
- .cm-editor pinned to font-size 1rem so the input matches the
  output pane (CodeMirror 6 defaults smaller)
- refreshLoaded(isInitial=true) on first load picks the hot model
  as the dropdown default — avoids the 5-15s disk reload on the
  first translation. Subsequent refreshes don't override the user's
  manual selection.
- document-level Shift-H / Shift-L cycle focus across controls
  (source → target → model → editor → button), suppressed when
  focus is inside CodeMirror so vim's viewport H/L still work.
